Keywords may be separated by AND and/or OR statements for greater control of the search results. For example, Music AND Theatre would generate a result that contains both words. However, for Music OR Theatre, the result returned would contain both or either words.

Exact matches can be searched for by enclosing keywords in double-quotes. For example, "Blue Roses" would generate a result which matches the exact string.

Brackets can be used for further control. For example, Microsoft and (keyboard or mouse or "visual basic").
